JavaScript

JavaScript (js) is an object-oriented, scripting programming language that finds its application primarily in web pages. Skilful use of objects, functions and variables defined using the language makes it possible to create interactive websites or even include entire applications in them.

The essence of using JavaScript is that there is no need to constantly reload the page in order to exploit its advantages. This is a good thing not only from the user’s perspective, but also from the server’s, which is relieved to some extent of the burden of constant document uploads.

For many developers, js happens to be the first ‘real’ programming language on which they build their skills. The simplicity and practical applications of JavaScript encourage rapid progress, opening the door to more difficult technologies.
